T2M Ethernet Interlaken IP

Interlaken IP

Description and Features

Interlaken interface provides full support for the Interlaken synchronous serial interface, compatible with Interlaken version 1.2 specification. Through its Interlaken compatibility, it provides a simple interface to a wide range of low-cost devices. Interlaken IP is proven in FPGA environment. The host interface of the Interlaken can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
